#!/bin/bash
#
# This is an example of a script to be put into
# /usr/lib/powersave/scripts/. Its name can then be used as an
# event name in /etc/sysconfig/powersave/events.
# Part of the powersave package.
#
# Stefan Seyfried, 2005
#
# First, we pull in the helper functions.
# This does the following:
# - expands PATH to the script path, sets the following variables:
# SCRIPT_DIR - the directory where the scripts are
# EV_ID - the event id, needed for SCRIPT_RETURN
# SCRIPT_RETURN - the binary that tells powersaved that we finished
# MYNAME - the name of this script
# LOGGER - command to log something: '$LOGGER "custom script logging"'
# SYSCONF_DIR - where the config files are lying around
# - sources $SYSCONF_DIR/common for basic config variabes.
# - provides some funcions:
# DEBUG - for logging depending on the $DEBUG variable
# EXIT - for exiting the script. Don't exit via "exit"!
# - sets a trap on exit so that even syntax errors in your scripts or
# unwanted codepaths or even foreign termination still lead to a controlled
# feedback for the powersaved via SCRIPT_RETURN
# This trap gets reset if you exit via the EXIT function - this is what it
# is for :-)

# this must be called to tell powersaved that processing of this
# event is finished. If your script is totally asynchronous, you
# can call this at the beginning of the script, before your code.
# in this case, powersaved will *not* wait for your script to finish.
# if you do not call this, weird things will happen.
